austin, texas, august 26th, 2005. away from the swirl of activity on 6th street, university of texas undergraduate laura ashley hall finds herself alone in an interrogation room contemplating the possibility of prison. police have already charged laura with hindering apprehension for driving boyfriend colton pitonyak into mexico after he kills his own girlfriend, 21-year-old jennifer cave. investigators also suspect laura of dismembering the corpse in the bathtub, cutting off the

head and the hands to prevent identification. >> didn't say anything about handling the body. >> i didn't touch the body. >> didn't say anything about handling things -- >> i didn't touch the hacksaw. >> when did we talk about a hacksaw? >> we didn't. i read it in the paper. >> do you believe everything you read it in the paper? >> no. >> how did you know there was a hacksaw involved. >> he told me he went and bought the hacksaw. he confessed that. >> laura is in the box for more than eight hours tweaking, revising, and sometimes in venting. >> he said that three people came into the apartment, one of them was -- they had guns. they came in shooting at them. he said he killed three people. >> did he say where the rest of them was supposed to be? >> yeah. >> what did he say? >> he said he dumped them. >> yet in between the

inaccuracies, detectives say they find a few nuggets of truth they need to further the case against colton. >> there's a bit of relief after the interrogation, because we were able to gather details that we would not have otherwise. >> despite her description of colton pitonyak as an intimidating drug user, who at one stagidge laura's story runs his tongue down a bloody knife, she refuses to testify at his 2007 trial for jennifer's murder. >> mr. pitonyak says he doesn't remember how it happened. when he essentially came out of the influence of alcohol and drugs, his friend jennifer cave was dead in his apartment. as far as all the mutilation and all of the aftermath, he blamed all of that on laura. >> colton is convicted of murder and sentenced to 55 years. and sometime prior to her own

trial, laura tattoos his name on her ankle, a bewildering choice her lawyer attributes to her instability. >> i think she is bipolar. she looks like miss america. coming into the trial she's smiling, all bad affect. tell me, is that relevant to the determination of whether she committed a crime. >> because she occupants not to take the stand at either trial, the best barometer of her character can be found on the interrogation tapes. >> colton owed about $2,000 to the asian mafia. he thought they were going to kill him over the money. >> yet prosecutors never allowed jurors to hear these statements. >> i've never seen the state miss an opportunity to air an

interrogation. >> i know it's embarrassing but i have to ask, was there intercourse or oral sex? >> uh-huh. >> what could be more important to show a jury than the callous disregard for the fact you're having sex feet away from the dismembered body of the young girl but they don't do it. the question is, why not? the flip side of that question is it's callous of the detectives who acted in reckless disregard to the common bounds of human decency. >> we did not introduce it at trial because we felt like it was man iipulative and self-serving and we would like to question her about her story. >> both the machete used in the dismemberment and gun fired will convince jurors she mutilated her rival for colton's affections.

on september 1st, 2007, laura is convicted of tampering with evidence, for cutting up jennifer's body and hindering apprehension for driving colton to mexico. nonetheless, because of a procedural dispute regarding the penal phase, laura decides to appeal her five-year sentence. this time bill bishop is prepared to let jurors hear the defendant's words, not from the interrogation but a series of recorded jailhouse phone conversations. >> i'm pretty mad. there's a lot of people that are going to pay for this. i hate them with a passion. >> among the targets of laura's anger, jennifer cave's mother. >> she's going down one way or another, that bitch. >> i remember the words. they are burned into my memory. i think the next question that was played in that conversation was what about that [ bleep ]

damn judge. she responds, when i get out of jail this time, i'm going to march down to his office and i'm going to bitch slap that mother [ bleep ] is what he said. of course the judge is sitting there listening, too. >> in july 2010, laura's appeal results in her sentence being doubled to 10 years. for detective david fugate, the information called from the interrogation of laura ashley hall ultimately fulfills his mission of giving voice to the dead. >> the bottom line is to find out the fabts of the case. it it's not necessary all about the conviction, it's about finding the truth. >> coming up. >> please don't ask me these questions. >> a florida teen is told he helped kill his elderly relatives.

>> if he didn't really remember it, it wouldn't come out as a lie here. >> he definitely took away in personal space that was there. t, and a smelly dog cage. and parked it at a mall. in texas. for two days. then put a febreze car vent clip on the dash and let in real people. it smells good. like laundry fresh out of like the dryer. yeah. a man fresh out of the shower. nailed it. oh yeah. proof. febreze car vent clips keep your car fresh. another way febreze helps you breathe happy. proof. febreze car vent clips keep your car fresh. by earning a degree from capella more iuniversity, you'll have the knowledge to make an impact in your company and take your career to an even greater place. let's get started at capella.edu.

often. i'll get this cranked up. >> you're going to have to reload the questions. >> computers, i think as we all know, although they are of great assistance, sometimes they are a problem. i've seen that happen in other investigations by other law enforcement agents. if the question is is that a ploy by the examiner, i don't believe it was. i don't have any evidence to indicate that it was. >> still, alex seems bothered by the mishap. >> i'll have you out of here before you know it. alex, do me a favor. take the microphone and hold it in front of your mouth. >> i've never heard of a voice analysis. i was doing everything i could to try to clear up whatever their thoughts were. i had no doubts on the answers i give him. i was extremely confident.
